Accuracy of Visual Assessment for Quantification of Myocardial Edema
Extension in Takotsubo Syndrome.
The aim of this study was to define the correlation between visual
qualitative method and semi-quantitative method for the study of the
extension of myocardial edema by CMR in patients with Takotsubo syndrome
(TTS). We analyzed 22 consecutive patients with a diagnosis of typical
apical TTS. A total of 374 myocardial segments were analyzed. A high
correlation between visual method and the semi-quantitative method of
the T2 SI ratio (Pearson’s r = 0.82, p <0.001) was found. In
the clinical setting the visual method provides a valid and reliable
quantification of myocardial edema extension in patients with TTS.
